' CASE A.

Be it known that I, JAMES E. WELLS, of

invented an Improvement in a Machine for Making Stove-Boilers, of whichthe following is a specification: V

The nature of my invention consists of the shaft A, as shown in theaccompanying drawings, attached to any frame suitable for the purpose,on which is secured the oblong head B, which is made hollow and in threepieces,- as shown in Figures 1 and 2. The ends O G are doweled into thesquare section of the head at each corner, to hold them in their properplaces and admit of thediead being expanded or contracted, as desirable,by a screwcam or any convenient device arranged inside the head D andoperated from the outadmit of the metal for a boiler being readily puton or removed from the head, and hold it necessary to make a boiler. Tothe novable frame E is attached the shaft F, directly over the head B,as shown in drawing, Fig. 1, to which are secured the crotch-hangers G,(shown more fully in Fig. 2,) on which are supported the shafts H, onwhich the tools or rolls Iare shaft H is attached, at the wire or topend of the boiler, the frame J, to which is secured the shoe K forrolling the metal over the wire;

also the roll L, running on the cam M on the which also rolls down theedge of the bottom Q over the burr; then the roll, Fig. 4, is adapted tobring the edges or seam over at an angle that may be rolled down by Fig.3, and either" burr, is kept to its proper position by connecting itwith the roll L by means of arms attached to a shaft placed across themovable frame E, and. not Shown in drawing.

To operate the machine the rolls are raised by any convenientarrangement, the metal (locked together) is placed. on the head, and theheads extended until it is tight. The roll N turns up the burr. Thebottom, with edges turned at right angles, is placed over the burr andsecured by the head S, and the seam rolled down. The shoe K is broughtagainst the edge of the metal by a lever, or in any effective ordesirable manner for turning the metal over the wire.

I claim as my invention 1. The adjustable head B, in combination withthe crotch-hangers Gr, shaft H, and rolls I, as described, and for thepurpose set forth.

2. The combination of the adjustable shoe K, frame J roll L, and cam M,substantially as described and shown, and for the purpose set forth.
